The "operating temperature range" is specified as +85 deg. C high limit.Does this really mean the MCU can operate with an ambient temperature of 85 C ? Only the maximum junction temperature is specific in the data sheet.
Hi Folks,Greetings!At my end have a STM32G474 HRTIM output driving a MOSFET gate driver such as IR2110.In some weird cases encountered, when the MOSFET blows up, it takes away with it thegate driver as well.Not in all cases, but in some situations, I...
I am using STM32H753 MCU. I generated my code using STM32Cube. The UART is configured to work on interrupt, baud rate is 19200. I sent 'A' many time but most of the time I am receiving "C1" in hex instead of "41" ('A' in ASCII).When I analyzed the da...
I wrote twice in here that I was going to get the board from mouser and infact I ordered the board just becasue of this webminar. I wrote it twice to be sure... and now I just received a message that my seat has been reassigned? what? is it supposed ...
Hi Guys,I working on one project where we need to enter into system bootloader for updating new firmware through the UART from software without using BOOT0 Pin.But I am facing problem in entering bootloader through software(user application).I had c...
My application is executed from flash and external SDRAM.I have a bootloader(seperat project) that saves the volatile SDRAM content on a QSPI.Normaly my application is applyed by a .hex file that is located on the SD-Card. So my bootloader can clearl...
I am using STM32H753 MCU. I am using ADC1 and ADC2 and calibrated the ADC offset using auto calibration function. But this function is not working properly. I am getting a difference of 50 counts on subsequent starts of my device. I checked this by g...
Refer to https://www.st.com/resource/en/datasheet/stm32f446re.pdfIn section 3.23 on PDF page 32, it says:"The devices embed four universal synchronous/asynchronous receiver transmitters (USART1, USART2, USART3 and USART6) and four universal asynchron...
